| Abstract: | We compute the fermionic radiative contributions to the decay in the framework of models with two Higgs doublets (2HDM), for the case of an on-shell and off-shell W. We show that, in the majority of the cases, current measurements of the parameter suggest and such decays could invalidate current charged Higgs searches or aid detection in the region . We find that the radiative corrections may approach 50% for small values of .
